1. What Is Mutual Fund Expense Ratio?

The Mutual Fund Expense Ratio represents the annual operating expenses as a percentage of the fund's average assets under management (AUM). It includes management fees, administrative costs, and other operational expenses incurred by the fund.

2. How Does The Calculator Work?

The calculator uses the Expense Ratio formula:

Where:

• \( ER \) — Expense Ratio (%)
• \( Total\ Expenses \) — Annual operating expenses in currency
• \( Avg\ AUM \) — Average Assets Under Management in currency

Explanation: The formula calculates what percentage of the fund's assets are used to cover annual operating expenses, providing investors with a standardized way to compare fund costs.

3. Importance Of Expense Ratio Calculation

Details: The expense ratio is crucial for investors to understand the true cost of owning a mutual fund. Lower expense ratios generally lead to higher net returns over time, making this calculation essential for investment decision-making and portfolio optimization.

4. Using The Calculator

Tips: Enter total annual operating expenses and average assets under management in the same currency. Both values must be positive numbers. The calculator will compute the expense ratio as a percentage.

5. Frequently Asked Questions (FAQ)

Q1: What Is Considered A Good Expense Ratio?
A: Generally, expense ratios below 0.5% are considered good for actively managed funds, while index funds often have ratios below 0.2%. The lower the ratio, the better for investors.
